Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein, and it will be apparent to those of ordinary skill in the art that the present application is not limited to the specific embodiments disclosed below.
Next, the present application will be described in detail with reference to the drawings, and in the detailed description of the embodiments of the present application, the cross-sectional views illustrating the structure of the device are not enlarged partially according to the general scale for convenience of illustration, and the drawings are only examples, which should not limit the scope of the protection of the present application. In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.
As described in the background section, in OLED display, the influence of the pixel arrangement on the actual display effect is very large, and the current general pixel arrangement has the defect of serious jaggy.
Fig. 1(a) shows a schematic diagram of a currently general pixel arrangement structure, and fig. 1(b) shows a schematic diagram of a pixel unit in the currently general pixel arrangement structure, as shown in fig. 1(a) and fig. 1(b), in the currently general pixel arrangement structure, one pixel unit includes two red sub-pixels 01, two blue sub-pixels 02 and one green sub-pixel 03, and geometric shapes of the red sub-pixel 01, the blue sub-pixel 02 and the green sub-pixel 03 are all rectangles, wherein the two red sub-pixels 01 are respectively located at two opposite sides of the green sub-pixel 03, and the two blue sub-pixels 02 are respectively located at the other opposite sides of the green sub-pixel 03.
The inventors have studied and found that, since each sub-pixel of one pixel unit is rectangular in the currently common pixel arrangement structure, the opening angle of the green sub-pixel 03 and the adjacent red and blue sub-pixels 01 and 02 is at right angles as indicated by the black bold line marks in fig. 1(b), thereby causing a serious jaggy defect in the arrangement direction of the pixel units, particularly in the lateral, longitudinal and oblique directions as indicated by the black bold line marks in fig. 1 (a).
In view of this, the embodiment of the present application provides a pixel arrangement 100, as shown in fig. 2, the pixel arrangement 100 includes: pixel rows 110 arranged in parallel along a first direction, the first direction being parallel to a plane in which the pixel arrangement is located;
each pixel row 110 includes pixel units 111 arranged repeatedly, fig. 3 shows a schematic structural diagram of one pixel unit in the pixel arrangement structure provided in the embodiment of the present application, and as shown in fig. 2 and fig. 3, each pixel unit 111 includes two first sub-pixels 10, two second sub-pixels 20, and a third sub-pixel 30, a connecting line of centers of the two first sub-pixels 10 and centers of the two second sub-pixels 20 forms a virtual rectangle 40, the two first sub-pixels 10 are respectively located at two ends of a diagonal line of the virtual rectangle 40, the two second sub-pixels 20 are respectively located at two ends of another diagonal line of the virtual rectangle 40, and a center of the third sub-pixel 30 is located in the virtual rectangle 40;
in each pixel unit 111, two opposite sides of the virtual rectangle 40 are parallel to the first direction, the other two opposite sides of the virtual rectangle 40 are perpendicular to the first direction, and the opening angle of the third sub-pixel 30 and the adjacent first sub-pixel 10 and second sub-pixel 20 in the first direction is an obtuse angle;
in each pixel row 110, adjacent pixel units 111 share one first sub-pixel 10 and one second sub-pixel 20, and third sub-pixels 30 in adjacent pixel units 111 are spaced apart by one first sub-pixel 10 and one second sub-pixel 20 shared by the adjacent pixel units 111.
It should be noted that, in the pixel arrangement structure provided in the embodiment of the present application, the pixel rows 110 are arranged in parallel along the first direction, and each pixel row 110 includes the pixel units 111 that are repeatedly arranged, that is, the pixel units 111 are repeatedly arranged along the first direction to form the pixel row 110, where the first direction may be a transverse direction of a plane where the pixel arrangement structure is located, as shown in the transverse direction in fig. 2, or a longitudinal direction of the plane where the pixel arrangement structure is located, as shown in the longitudinal direction in fig. 2, or an oblique direction of the plane where the pixel arrangement structure is located, as shown in the oblique direction in fig. 2, which is not limited in this application, depending on the situation.
It should be noted that the center of the first sub-pixel 10 is the geometric center of the shape of the first sub-pixel, for example, as shown in fig. 2, if the shape of the first sub-pixel 10 is a regular pentagon, the center of the first sub-pixel 10 is the intersection of the bisectors of any two angles of the regular pentagon. Similarly, the center of the second sub-pixel 20 is the geometric center of the shape of the second sub-pixel, and the center of the third sub-pixel 30 is the geometric center of the shape of the third sub-pixel.
In each pixel unit 111, the connection line of the centers of the two first sub-pixels 10 and the centers of the two second sub-pixels 20 forms a virtual rectangle 40, the two first sub-pixels 10 are respectively located at two ends of a diagonal line of the virtual rectangle 40, the two second sub-pixels 20 are located at two ends of the other diagonal line of the virtual rectangle 40, the center of the third sub-pixel 30 is located in the virtual rectangle 40, and two opposite sides of the virtual rectangle 40 are parallel to the first direction, the other two opposite sides of the virtual rectangle 40 are perpendicular to the first direction, that is, as shown in fig. 2, in each pixel unit 111, the center of one first sub-pixel 10 is connected with the center of one second sub-pixel 20 along the first direction to form a side length of the virtual rectangle 40 along the first direction, the line connecting the center of the one first sub-pixel 10 and the center of the other second sub-pixel 20 forms a side length of the virtual rectangle 40 perpendicular to the first direction.
Since the pixel rows 110 are arranged in parallel along the first direction, as shown in fig. 2, a connecting line between the center of each first sub-pixel 10 of one pixel unit 111 in the ith pixel row 110 and the center of each first sub-pixel 10 of the pixel unit 111 adjacent to and arranged the same as the pixel unit in the (i + 1) th pixel row forms a parallelogram, and i is an integer not less than 1. Similarly, as shown in fig. 2, a line connecting the centers of the second sub-pixels 20 of one pixel unit 111 in the ith pixel row 110 and the centers of the second sub-pixels 20 of the pixel units 111 adjacent to and arranged in the same row in the (i + 1) th pixel row also forms a parallelogram.
The arrangement manner of the adjacent pixel rows 110 is not limited in the present application, and optionally, in an embodiment of the present application, the two adjacent pixel rows 110 are completely the same; optionally, in another embodiment of the present application, two adjacent pixel rows 110 are arranged in a staggered manner. In addition, the application does not limit whether the first sub-pixel 10 and/or the second sub-pixel 20 are shared between the adjacent pixel rows 110, as the case may be.
It should be noted that the geometric area of the first sub-pixel 10 is larger than the area of its actual light emitting unit, for example, as shown in fig. 2, the geometric shape of the first sub-pixel 10 is a regular pentagon which includes a small pentagon which is the actual light emitting unit of the first sub-pixel, and the geometric area of the first sub-pixel is the area of a large pentagon which surrounds the small pentagon, because in the actual process, it is necessary to leave design margins for the pixel, and some of these margins are actually not light emitting. Then, as shown in fig. 2 and 3, in each pixel unit 111, the opening angle of the third sub-pixel 30 and the first sub-pixel 10 and the second sub-pixel 20 adjacent thereto in the first direction is an obtuse angle, specifically, the opening angle of the light emitting unit of the third sub-pixel 30 and the light emitting unit of the first sub-pixel 10 and the second sub-pixel 20 adjacent thereto in the first direction is an obtuse angle.
For example, as shown in fig. 3, in one pixel unit 111, a point of the light-emitting unit of the third sub-pixel 30 closest to the left side is set as an O point, a point of the light-emitting unit of the first sub-pixel 10 adjacent to the third sub-pixel 30 closest to the left side in the first direction is set as an a point, and a point of the light-emitting unit of the second sub-pixel 20 adjacent to the third sub-pixel 30 closest to the left side in the first direction is set as a B point, where, in the first direction, a connection line between the center of the first sub-pixel 10 adjacent to the third sub-pixel 30 and the center of the second sub-pixel 20 adjacent to the third sub-pixel 30 is parallel to the first direction and is one side length of the virtual rectangle 40 in the first direction, and then, the opening angle of the light-emitting unit of the third sub-pixel 30 and the light-emitting unit of the first sub-pixel 10 and the light-emitting unit of the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction is ≧ B, the flare angle AOB is an obtuse angle, so that the sawtooth sense is reduced, and the display effect is improved.
Of course, in each pixel unit 111, the opening angle of the light emitting unit of the third sub-pixel 30 and the light emitting unit of the first sub-pixel 10 and the light emitting unit of the second sub-pixel 20 adjacent to the light emitting unit of the third sub-pixel 30 in the first direction is not necessarily the same as that shown in fig. 3, and the angle between the leftmost O point of the light emitting unit of the third sub-pixel 30 and the leftmost a point of the light emitting unit of the first sub-pixel 10 adjacent to the light emitting unit in the first direction and the leftmost B point of the light emitting unit of the second sub-pixel 20 adjacent to the light emitting unit in the first direction is the opening angle as long as two rays emitted from the leftmost O point of the light emitting unit of the third sub-pixel 30 are just in contact with the light emitting unit of the first sub-pixel 10 and the light emitting unit of the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction, respectively, at this time, the light emitting unit of the third sub-pixel 30 and the light emitting unit of the first sub-pixel 10 and the light emitting unit of the second sub-pixel 20 adjacent thereto in the first direction are located outside the opening angle.
In addition, in fig. 2 and fig. 3, the light emitting unit of the third sub-pixel 30 is a quadrangle, and only one vertex O at the leftmost side of the quadrangle is taken as an example for explanation, it is obvious that this is not limited in this application, and when the leftmost side of the light emitting unit of the third sub-pixel 30 is not a vertex but a line segment or a plurality of vertices, according to practical situations, an appropriate point may be selected as the O point on the light emitting unit of the third sub-pixel 30, so that the opening angle between the O point on the light emitting unit of the third sub-pixel 30 and the light emitting unit of the first sub-pixel 10 and the light emitting unit of the second sub-pixel 20 adjacent to the third sub-pixel 30 in the first direction is an obtuse angle, thereby reducing the jagged feeling and improving the display effect.
Therefore, compared with the current general pixel arrangement structure in which the opening angles of the green sub-pixel and the adjacent red sub-pixel and blue sub-pixel are right angles in the arrangement direction of the pixel units, the pixel arrangement structure provided in the embodiment of the present application has the advantage that in the arrangement direction of the pixel units (i.e. the first direction), the opening angle of the third sub-pixel and the first sub-pixel and the second sub-pixel adjacent to the third sub-pixel in the first direction is an obtuse angle, which is more gentle than the right angle, so that the jaggy feeling is reduced, and the display effect is improved.
On the basis of the above embodiment, optionally, in an embodiment of the present application, the first sub-pixel 10 and the second sub-pixel 20 are both polygons with the number of edge lengths not less than 5, and the third sub-pixel 30 is a quadrangle or a hexagon. For example, as shown in fig. 2 and 3, the first sub-pixel 10 and the second sub-pixel 20 are both pentagons; as shown in fig. 4, the first subpixel 10 and the second subpixel 20 are both hexagonal-shaped; as shown in fig. 5, the first sub-pixel 10 and the second sub-pixel 20 are each octagonal.
Alternatively, as shown in fig. 3 to 5, the first sub-pixel 10 and the second sub-pixel 20 are both regular polygons.
Optionally, in another embodiment of the present application, the first sub-pixel 10 and the second sub-pixel 20 are both circular or elliptical, and the third sub-pixel 30 is a quadrangle or a hexagon. Alternatively, as shown in fig. 6, the first sub-pixel 10 and the second sub-pixel 20 are both circular.
On the basis of any of the above embodiments, optionally, in an embodiment of the present application, the first sub-pixel 10 and the second sub-pixel 20 have the same shape.
On the basis of any of the above embodiments, optionally, in an embodiment of the present application, as shown in fig. 3 to 6, in each pixel unit, the center of the third sub-pixel 30 coincides with the center of the virtual rectangle 40.
It should be noted that, in each of the above embodiments, the first sub-pixel 10 and the second sub-pixel 20 are set to be in a polygonal shape, a circular shape, or an elliptical shape with the number of side lengths not less than 5, and the third sub-pixel 30 is in a quadrangular shape or a hexagonal shape, so that when the polygonal, circular, or elliptical first sub-pixel 10, the polygonal, circular, or elliptical second sub-pixel 20, and the quadrangular or hexagonal third sub-pixel 30 are combined to form the pixel unit 111, the outer corner after stitching is large because the inner angle of each sub-pixel is small, so that the jaggy feeling can be reduced, as shown in fig. 2, it can be seen that the jaggy feeling of line display is reduced in both the first direction and the direction perpendicular to the first direction, and in the oblique direction intersecting the first direction.
Further, the inventors have studied and found that, in the currently general pixel arrangement structure, as shown in fig. 1(a), in the display edge region, specifically, as the leftmost region and the bottommost region of the pixel arrangement structure in fig. 1(a), since the central connecting line of the red sub-pixel 01 and the blue sub-pixel 02 is parallel to the pixel unit arrangement direction, and the green sub-pixel 03 is located inside the central connecting line of the red sub-pixel 01 and the blue sub-pixel 02, edge color cast occurs in the display edge region, which affects the display effect; similarly, as shown in the topmost and rightmost regions of the pixel arrangement structure in fig. 1(a), since the center connecting line of the red sub-pixel 01 and the blue sub-pixel 02 is parallel to the pixel unit arrangement direction, and the green sub-pixel 03 is located outside the center connecting line of the red sub-pixel 01 and the blue sub-pixel 02, edge color cast may also occur in the display edge region, which may affect the display effect.
In view of this, optionally, in an embodiment of the present application, as shown in fig. 2 and 3, a side length of the virtual rectangle 40 along the first direction spans the third sub-pixel 30 whose center is located in the virtual rectangle 40. At this time, in the pixel unit arrangement direction (i.e. in the first direction), the first sub-pixel 10, the third sub-pixel 30 and the second sub-pixel 20 are sequentially arranged, so that the first sub-pixel 10, the second sub-pixel 30 and the second sub-pixel 20 are uniformly arranged in the display edge region, and the number of the first sub-pixel, the second sub-pixel and the second sub-pixel is equal, thereby effectively improving the edge color cast in the display edge region and enhancing the display effect.
As is known from the foregoing, the arrangement of the adjacent pixel rows 110 is not limited in the present application, but it is considered that the edge color shift occurs not only in the arrangement direction of the pixel units (i.e., the first direction), but also in the direction perpendicular to the first direction. In the direction perpendicular to the first direction, if the pixel rows 110 are completely repeatedly arranged, in the display edge region perpendicular to the first direction, a phenomenon in which the first sub-pixels 10 and the second sub-pixels 20 are alternately arranged occurs, resulting in edge color cast. Therefore, further, optionally, in an embodiment of the present application, as shown in fig. 2 and fig. 3, a center of the virtual rectangle 40 corresponding to one pixel unit 111 in the ith pixel row 110 and a center of the virtual rectangle 40 corresponding to one pixel unit 111 adjacent to the pixel unit in the (i + 1) th pixel row 110 are not on one virtual straight line along a second direction, the second direction is parallel to a plane where the pixel arrangement structure is located, the second direction is perpendicular to the first direction, and i is an integer not less than 1.
That is, the center of the virtual rectangle 40 corresponding to one pixel unit 111 in the ith pixel row 110 and the center of the virtual rectangle 40 corresponding to one pixel unit 111 adjacent to the pixel unit in the (i + 1) th pixel row 110 are located at both sides of a virtual straight line along the second direction, that is, the virtual rectangle 40 corresponding to one pixel unit 111 in the ith pixel row 110 and the virtual rectangle 40 corresponding to one pixel unit 111 adjacent to the pixel unit in the (i + 1) th pixel row 110 are not completely repeatedly arranged along the second direction but are arranged with a shift in the second direction, so that the first sub-pixel 10 and the second sub-pixel 20 of one pixel unit 111 in the ith pixel row 110 and the third sub-pixel 30 of one pixel unit 111 adjacent to the pixel unit in the (i + 1) th pixel row 110 are sequentially arranged in the second direction, furthermore, in the second direction, the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 are sequentially arranged, so that the edge color cast is improved in the display edge area along the second direction, and the display effect is improved.
In this application, the order in which the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are sequentially arranged along the second direction is not limited. Specifically, as shown in fig. 2, for the first row, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are sequentially arranged along the second direction; for the second row, the third sub-pixel 30, the second sub-pixel 20 and the first sub-pixel 10 are sequentially arranged along the second direction; for the third row, the second sub-pixel 20, the first sub-pixel 0 and the third sub-pixel 30 are sequentially arranged in this order; for the fourth row, the third sub-pixel 30, the first sub-pixel 10 and the second sub-pixel 20 are sequentially arranged in this order.
On the basis of the foregoing embodiment, optionally, in an embodiment of the present application, as shown in fig. 2, in the second direction, the center of the first sub-pixel 10 and the center of the second sub-pixel 20 of one pixel unit 111 in the ith pixel row 110 and the center of the third sub-pixel 30 of one pixel unit 111 adjacent to the ith pixel row 110 in the ith pixel row 110 are located on one virtual straight line along the second direction, so as to further improve the uniformity of the sequential arrangement of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 along the second direction, further eliminate edge color cast, and improve the display effect.
On the basis of the above embodiments, optionally, in an embodiment of the present application, as shown in fig. 2, the ith pixel row and the (i + 2) th pixel row are repeatedly arranged, so that each pixel row is only divided into two types, and the process steps are simplified while the jaggy defect and the edge color cast defect are improved.
On the basis of the above embodiment, optionally, in an embodiment of the present application, as shown in fig. 7, in each pixel unit 111, the third sub-pixel 30 is axisymmetric along a first virtual straight line 50, the first virtual straight line 50 is a virtual straight line parallel to the first direction and passing through a center of the virtual rectangle 40, the first sub-pixel 10 and the second sub-pixel 20 located on one side of the third sub-pixel 30 are also axisymmetric along the first virtual straight line 50, and the first sub-pixel 10 and the second sub-pixel 20 located on the other side of the third sub-pixel 30 are also axisymmetric along the first virtual straight line 50.
On the basis of the above embodiment, optionally, in an embodiment of the present application, as shown in fig. 7, in each pixel unit 111, the third sub-pixel 30 includes a first side length 31 and a second side length 32 that are connected to each other and are axisymmetric along the first virtual straight line 50, and a third side length 33 and a fourth side length 34 that are connected to each other and are axisymmetric along the first virtual straight line 50, and the first side length 31 and the third side length 33 are axisymmetric along a second virtual straight line 60, and the second side length 32 and the fourth side length 34 are also axisymmetric along the second virtual straight line 60, where the second virtual straight line 60 is a virtual straight line that is perpendicular to the first direction and passes through the center of the virtual rectangle 40;
in each pixel unit 111, two first sub-pixels 10 are respectively in contact with the first side length 31 and the fourth side length 34 of the third sub-pixel 30, and two second sub-pixels 20 are respectively in contact with the second side length 32 and the third side length 33 of the third sub-pixel 30.
Since in each pixel row 110, the adjacent pixel units 111 share one first sub-pixel 10 and one second sub-pixel 20, and the third sub-pixels 30 in the adjacent pixel units 111 are spaced apart by one first sub-pixel 10 and one second sub-pixel 20 shared by the adjacent pixel units, as shown in fig. 2, in one pixel unit 111, the length of the virtual rectangle 40 along the first direction needs to span the third sub-pixel 30, and the length of the virtual rectangle 40 along the length perpendicular to the first direction may not need to span the third sub-pixel 30. In order to further make the arrangement of the pixel units 111 in the pixel arrangement structure 100 more compact and improve the display effect, on the basis of any of the above embodiments, optionally, in an embodiment of the present application, a side length of the virtual rectangle 40 along the first direction is greater than a side length of the virtual rectangle 40 perpendicular to the first direction.
Specifically, in an embodiment of the present application, a side length of the virtual rectangle 40 along the first direction is 2 times a side length of the virtual rectangle 40 perpendicular to the first direction, so that a display scale is better.
On the basis of any of the above embodiments, optionally, in an embodiment of the present application, the first sub-pixel 10 is a red sub-pixel, the second sub-pixel 20 is a blue sub-pixel, and the third sub-pixel 30 is a green sub-pixel.
Optionally, in another embodiment of the present application, the first sub-pixel 10 is a blue sub-pixel, the second sub-pixel 20 is a red sub-pixel, and the third sub-pixel 30 is a green sub-pixel.
In order to more clearly demonstrate the display effect of the pixel arrangement structure provided by the embodiment of the present application, fig. 8 shows an overall schematic view of the pixel arrangement structure provided by the embodiment of the present application, as shown in fig. 8, each of the first sub-pixel 10 and the second sub-pixel 20 may be a polygon, a circle or an ellipse with the number of edge lengths not less than 5, and the third sub-pixel 30 may be a quadrangle or a hexagon, so that in each pixel unit 111, the opening angle of the third sub-pixel 30 and the first sub-pixel 10 and the second sub-pixel 20 adjacent to the third sub-pixel in the first direction is an obtuse angle, thereby reducing the jaggy feeling and improving the display effect when displaying horizontal lines, vertical lines and oblique lines; moreover, the pixels are arranged in a staggered manner in rows, so that the pixels in the outermost edge area are uniformly arranged in the first sub-pixel, the second sub-pixel and the third sub-pixel in equal number no matter in the row direction or the column direction as shown in fig. 8, thereby greatly reducing color cast in the display edge area and further improving the display effect; in addition, as can also be seen from fig. 8, the pixel units are closely arranged, and the space utilization rate can be improved, so that the display scale is better.
The embodiment of the present application further provides a display panel 200, which includes any one of the pixel arrangement structures described above, wherein a plane of the pixel arrangement structure is parallel to a plane of the display panel.
The embodiment of the present application further provides a display device, and as shown in fig. 9, the display device 300 includes the display panel 200. The display device can be any electronic equipment with a display function, such as a touch display screen, a mobile phone, a tablet computer, a notebook computer, an electronic paper book or a television.
In summary, in the pixel arrangement structure provided in the embodiment of the present application, in the arrangement direction of the pixel units (i.e. in the first direction), the opening angle of the third sub-pixel and the opening angle of the first sub-pixel and the second sub-pixel adjacent to the third sub-pixel in the first direction are obtuse angles, and are more gradual than that of the current general pixel arrangement structure in which the opening angle of the green sub-pixel and the opening angle of the red sub-pixel and the blue sub-pixel adjacent to the green sub-pixel are right angles, so that the jaggy is reduced, and the display effect is improved. Furthermore, the length of the virtual rectangle corresponding to each pixel unit along the first direction spans the third sub-pixel whose center is located in the virtual rectangle, so that the first sub-pixel, the second sub-pixel and the second sub-pixel are uniformly arranged in the display edge area, and the number of the first sub-pixel, the second sub-pixel and the second sub-pixel are equal, thereby effectively improving the edge color cast of the display edge area, and further improving the display effect. Furthermore, adjacent pixel rows are arranged in a staggered manner, so that the uniformity of the sequential arrangement of the first sub-pixel, the second sub-pixel and the third sub-pixel along the second direction (perpendicular to the first direction) is further improved, the edge color cast is further eliminated, and the display effect is improved.
